Summary
The “span” command views or modifies a T1 CAS span record.
Description
The “span” command is used to view or modify a T1 CAS span record in the database. This tells the
system whether the span should be active, various characteristics of the span, and the mapping between
trunks and internal port numbers.
system whether the span should be active, various characteristics of the span, and the mapping between
trunks and internal port numbers.
The following characteristics are set by the “span” command:
•
Framing — D4 or ESF. The framing protocol used on this span. This is determined by the service
provider. We recommend using ESF only.

•
Zero code suppression — none, B8ZS, or jammed bit. This protocol is determined by the service
provider. We recommend using B8ZS only.
provider. We recommend using B8ZS only.
•
Timing — external or internal. This determines whether the span is permitted to supply trunk timing
for the system. Specify external if the span is connected to the public network or a trusted system.
At least one span should always be designated external.
for the system. Specify external if the span is connected to the public network or a trusted system.
At least one span should always be designated external.
•
External sync priority — a number (1-255) or never that controls the priority (1 is highest, 255 is
lowest) of the spans that are set for external timing. The system picks the highest priority operational
span to provide the timing. If two spans have the same priority, the lower numbered span is used.

•
Remote loopback to network? — y or n. If yes, this puts the span into a loopback mode for testing
from the remote end. For normal operation, set to n.

•
Internal data loopback? — y or n. If yes, this causes the span to loop back locally for running
diagnostics. For normal operation, set to n.

Options
After typing
span
and pressing Enter, the following menu appears:
•
1) View DTI span record(s) — prompts the user to select a specific span or all spans. The system
displays whether the card is active, the characteristics of the span, and the port number of each trunk.
displays whether the card is active, the characteristics of the span, and the port number of each trunk.
•
2) Modify DTI span record — prompts the user to select a specific span, then prompts the user for
whether the span should be active, the characteristics of the span, and the port number assignment
for each trunk.

•
x) Exit — exits the “span” command.
Note
For each voice processor unit, the spans are numbered 0-4. Trunks on a span are numbered 1-24. Ports
are numbered 0-119 (or the number of licensed access ports minus 1). There are up to four span records
for each Smart Blade.

for each Smart Blade.
Note
The span record is referenced by both a Smart Blade record (see the “blade” command) and each port
record (configured from the port command and MeetingTime). It is important to be sure that these
references are consistent. If a port is referenced in a span record, the corresponding port record must
reference that span.
